Jax Pavan was born to Sug and Annja Pavan on Coruscant. He was an average young boy who attended public school and aspired to become a neurosurgeon. However, med school proved to be too big a challenge for Pavan, and he dropped out. He took career training at a local tech school and yearned for a career in criminal justice. That also did not pan out, and faced with mounting student loans, Pavan took a job at a local supermarket.

He worked at the supermarket for many years, eventually becoming the assistant manager. He never did achieve notoriety, and became worried about attending his upcoming high school reunion, feeling that all his classmates had reached their goals and were financially secure. However, the high school had the lowest turn out of graduates on Coruscant, and his classmates were working dead-end jobs as well.
